A histone modification, a covalent post-translational modification (PTM) to histone proteins, includes methylation, phosphorylation, acetylation, ubiquitylation, and sumoylation, etc. In general, histone modifications are catalyzed by specific enzymes that act predominantly at the histone N-terminal tails involving amino acids such as lysine or arginine, as well as serine, threonine, tyrosine, etc. The PTMs made to histones can impact gene expression by altering chromatin structure or recruiting histone modifiers. Histone modifications act in diverse biological processes such as transcriptional activation/inactivation, chromosome packaging, and DNA damage/repair. Deregulation of histone modification contributes to many diseases, including cancer and autoimmune diseases.

MCE owns a unique collection of 931 bioactive compounds targeting Epigenetic Reader Domain, HDAC, Histone Acetyltransferase, Histone Demethylase, Histone Methyltransferase, Sirtuin, etc. Histone Modification Research Compound Library is a useful tool for histone modification research and drug screening.

Tyrostatin is a peptide inhibitor isolated from Kitasatospora sp. 55. It has a Ki value of 6 nM against serine carboxyl protease (PSCP) from Pseudomonas sp. 101, a Ki value of 2.1 nM against carboxyl protease (XSCP) from Xanthomonas sp. T-22, and a Ki value of 2.6 nM against carboxyl protease (PCP) from Pseudomonas sp. 101. Tyrostatin forms a reversible covalent hemiacetal bond with Ser287 at the active site of PSCP, where Tyr at the P1 position and Leu at the P2 position occupy the S1-S4 subsites of the enzyme. Tyrostatin inhibits the activity of XSCP, specifically blocks the autocatalytic maturation process of PCP precursor under acidic conditions, and also inhibits the protease activity of mature and recombinant PCP in a dose-dependent manner. Tyrostatin does not inhibit KSCP or alcohol-resistant protease J-4, and can serve as a tool for identifying the catalytic residues of PCP .

Reactive oxygen species responsive hydrogels are a novel class of smart hydrogels, formed by the cross-linking of ROS-responsive modules through covalent, coordination, or supramolecular interactions. Due to the introduction of these ROS-responsive modules, these hydrogels exhibit a sensitive response to the oxidative stress microenvironment present in organisms. PVA-TSPBA hydrogel is a hydrogel formed by the cross-linking polymerization of polyvinyl alcohol (PVA) and the reactive oxygen species-sensitive cross-linking agent N1-(4-benzyl borate)-N3-(4-phenyl borate)N1,N1,N3,N3-tetramethyl-1,3-propanediamine (TSPBA). This hydrogel consists of two parts: a boric acid precursor (TSPBA) and an aqueous solution of PVA. The boric acid bonds on TSPBA and the hydroxyl groups on PVA rapidly cross-link to form borate ester bonds, thus forming the hydrogel.

P6-Aggrate is a fluorescent probe for aggregated proteome detection. P6-Aggrate specifically recognizes amorphous aggregated proteomes through non-covalent reversible binding, and its fluorescence enhances after heat-induced protein aggregation. P6-Aggrate reflects the polarity and compactness heterogeneity within aggregated proteomes via emission wavelength shift: short-wavelength emission (blue shift) corresponds to large aggregates with high compactness, while long-wavelength emission (red shift) corresponds to small spots with low compactness (Ex/Em = 488/520-580 nm). P6-Aggrate enables reversible monitoring of the dynamic processes of formation and clearance of stress-induced proteome aggregation such as that induced by MG132 (HY-13259) in living cells. P6-Aggrate can be used in studies related to protein homeostasis imbalance, neurodegenerative diseases and protein aggregation .
